As Bob Ringler noted in his post from Sat, around 1225 EDT on Sat (21 Aug) the White Pelican came out of its thermal and began a long slow glide to the SW. I was on the VA shoreline just N of the Wilson Bridge at the time and watched it through my Questar until it was quite close to the shoreline. It crossed into VA just S of the bridge and seemed to be on a faily level path (occasional flapping) when we lost it behind trees and towers to the SW. I spent 1250 to 1440 EDT looking through the shorebirds at the mouth of Hunting Creek (primarily from the GW Parkway bridge). While I was scoping birds to the West, a birder looking East from the bridge found the White Pelican on the exposed flats E of the mouth of the creek. It remained there as the tide came in (low tide was c 1125). We showed it to a NPS ranger and some volunteers who passed by on bikes. I watched it on and off from c 1330 to 1430: Standing, preening, and scratching head while the bar was exposed; swimming back and forth, fishing, playing with a stick (that it would pick up, hold cross-wise in bill, drop, probe about, and pick up again ... for 2 or 3 minutes) after the bar was flooded. Just after 1430 it flew off E over river. First slow flapping to climb and circle upwards, then soaring about over cove in front of "Washington Harbor" clearing, then crossing out of sight upriver. [Got excellent views from 200-250 m in nice light while the bird was on the bar and water.] [The cove at the mouth of Hunting Creek is in VA (with the boundary running just W of S from the Jones Point corner of DC); the main channel and the Hydrilla mats E of it are MD waters.] [Around 1825, while returning from a walk down the Dyke Marsh haul road, I scoped N under the Wilson Bridge from the point just N of the Belle Haven marina boat ramp. Through the Questar, the pelican was visible well beyond the bridge in line with the mouth of Oxon Creek.] On Sunday the midday low tide was about 1220. I got to the mouth of Hunting Creek about 1350. The pelican was present over the already flooded bar to the East of the GW Parkway bridge. (Had a camera and got a few distant shots.) It remained until c 1455, when it flew off to the E, circled upwards, and headed up river. I searched up river from 1520 to 1700 without success. (Checking from Jones Point up to Alexandria waterfront at Duke St, and scoping far upriver and along MD shores from Blue Plains STP south.) A couple of people were at the foot of Jones Pt Road most of this time and they also failed to see the bird. The reason for our failure became clear when I headed home: the pelican was again over the flooded bar at the mouth of Hunting Creek at 1705-1730. [It was not there at 1930.] Sherman Suter Alexandria, VA 22307
